RESUMO

Downs syndrome (DS) is the most common genetic disorder and it is caused by the trissomy of 21 chromosome. It is characterized by mental retardation, physical alterations and several systemic co morbidities. The aim of this study was to evaluate behavior and systemic alterations with dental implications in DS patients and discuss the dental management of these patients. We evaluate 52 patients with DS under dental treatment at the Special Care Dentistry Center of the School of Dentistry, University of São Paulo. The guardians were interviewed about systemic co morbidities based on a special chart developed for this research. The following systemic alterations were analyzed: cardiac, respiratory, neurological and behavior, immunological, hematological, endocrine (thyroid disorders and diabetes), infeccious diseases and joint alterations. Patients were submitted to complementary exams such as : blood pressure and glucose levels, body mass index, CBC, coagulagrama hormone (TSH), total triiodothyronine (T3), free thyroxine (FT4), total thyroxine (T4), total cholesterol and fractions, triglycerides, glycated hemoglobin, serology for hepatitis B and C, aspartate aminotransferase (AST), alanine aminotransferase (ALT). The results show that the most frequent systemic alterations were respiratory alterations, pneumonia being the most common and its incidence was inversely proportional to the age of the patients, followed by cardiac abnormalities, while 13 patients had only one, and four had multiple abnormalities, and the heart murmur was the most frequent cardiac alterations. Within the neurological and behavioral disorders, 37 patients had at least one characteristic of early Alzheimer\ s disease. Ten patients had hypothyroidism, 7 patients had subclinical hypothyroidism, 3 patients state of pre-diabetes, two patients a state of pre-hypertension. The total cholesterol levels were desirable in 36 patients, and triglycerides in 42 patients, with inverse correlation to body mass index. 37 patients showed some degree of overweight or obesity. CBC showed 5 patients with anemia and 10 with leukopenia. 24 patients were vaccinated for hepatitis A, and 26 for hepatitis B, but 12 patients did not show seroconversion against the vaccine. One patient was diagnosed with hepatitis C. As the presence of atlanto-axial instability, eight patients reported their presence. We can conclude that many of the systemic alterations reported in the literature are present in patients with DS seen at CAPE. It is necessary for the dentist to know the medical history of patients with SD before the dental treatment, and it is necessary to adjust the treatment according to each systemic alterations presented by patients in order to provide a safe and effective treatment.
